  • Getting to Know Computers
    Computer Basics Getting to Know Computers Page 1 What is a Computer? A computer is an electronic device that manipulates information, or "data." It has the ability to store, retrieve, and process data. You can use a computer to type documents, send email, and browse the internet. You can also use it to handle spreadsheets, accounting, database management, presentations, games, and more. Watch the video to learn about different types of computers. Watch the video (2:39). Need help? Computers Simplified For beginning computer users, the computer aisles at an electronics store can be quite a mystery, not to mention overwhelming. However, computers really aren't that mysterious. All types of computers consist of two basic parts: Hardware is any part of your computer that has a physical structure, such as the computer monitor or keyboard. Software is any set of instructions that tells the hardware what to do. It is what guides the hardware and tells it how to accomplish each task. Some examples of software are web browsers, games, and word processors such as Microsoft Word. A motherboard (hardware) Microsoft Word (software) Anything you buy for your computer can be classified as either hardware or software. Once you learn more about these items, computers are actually very straightforward. The first electronic computer, the Electronic Numerical Integrator and Computer (ENIAC), was developed in ©1998-2013 Goodwill Community Foundation, Inc. All rights reserved. 1946. It took up 1,800 square feet and weighed 30 tons. Page 2 What are the Different Types of Computers? When most people hear the word "computer," they think of a personal computer such as a desktop or laptop computer.

    Written by Published by Nick Tredennick DynamicSilicon Gilder Publishing, LLC Vol. 2, No. 9 The Investor's Guide to Breakthrough Micro Devices September 2002 Lessons From the PC he worldwide market for personal computers has grown to 135 million units annually. Personal com- puters represent half of the worldwide revenue for semiconductors. In July of this year, PC makers Tshipped their billionth PC. I trace the story of the personal computer (PC) from its beginning. The lessons from the PC apply to contemporary products such as switches, routers, network processors, microprocessors, and cell phones. The story doesn’t repeat exactly because semiconductor-process advances change the rules. PC beginnings Intel introduced the first commercial microprocessor in 1971. The first microprocessors were designed solely as cost-effective substitutes for numerous chips in bills of material. But it wasn’t long before micro- processors became central processing units in small computer systems. The first advertisement for a micro- processor-based computer appeared in March 1974. Soon, companies, such as Scelbi Computer Consulting, MITS, and IMSAI, offered kit computers. Apple Computer incorporated in January 1977 and introduced the Apple II computer in April. The Apple II came fully assembled, which, together with the invention of the spreadsheet, changed the personal computer from a kit hobby to a personal business machine. In 1981, IBM legitimized personal computers by introducing the IBM Personal Computer. Once endorsed by IBM, many businesses bought personal computers. Even though it came out in August, IBM sold 15,000 units that year. Apple had a four-year head start. When IBM debuted its personal computer, the Apple II dom- inated the market.

  • DATAC BUS MONITOR Stanley M. Novackl, III and Robert J. Thomas, Jr. Ohio University Athens, Ohio INTRODUCTION the Digital Autono
    DATAC BUS MONITOR Stanley M. Novackl, III and Robert J. Thomas, Jr. Ohio University Athens, Ohio INTRODUCTION The Digital Autonomous Terminal Access Communications (DATAC) bus is a multiple transmitter data bus developed by the Boeing Company to interconnect various aircraft systems. Figure I shows a typical DATAC bus installation for the NASA B-737 aircraft. Essentially a local-area network for use aboard air- liners, it uses Carrier-Sense, Multiple Access with Collision Detection (CSMA/CD) protocol. This means that operation of the bus relies on each system that uses a certain set of rules when it "broadcasts" a message via the bus. In the simplest mode of operation, each system listens to determine if the bus is currently in use. If no bus activity is detected, each system enables a counter with a unique value. The first counter to reach its terminal value assumes the right to broadcast over the bus and transmits its data. When the other terminals detect this bus activity, even if their respective timers are active, their timers are reset and are disabled until bus inactivity is again detected. When the current broadcasting system has concluded its transmission, its timer is disabled until all other systems have broadcast. This ensures that one system will not monopolize the bus. The system with the next shortest terminal count will expire next, and it will access the bus. The process is repeated until all systems have had the opportunity to transmit. After all stations have transmitted their messages, the process repeats itself. A liability of this autonomous protocol is that it is not possible to interrogate a specific subsystem to determine its current operating condition.

  • Schumpeterian Competition and Diseconomies of Scope; Illustrations from the Histories of Microsoft and IBM
    Schumpeterian competition and diseconomies of scope; illustrations from the histories of Microsoft and IBM Timothy Bresnahan Shane Greenstein Rebecca Henderson Working Paper 11-077 Copyright © 2011 by Timothy Bresnahan, Shane Greenstein, Rebecca Henderson Working papers are in draft form. This working paper is distributed for purposes of comment and discussion only. It may not be reproduced without permission of the copyright holder. Copies of working papers are available from the author. Schumpeterian competition and diseconomies of scope; illustrations from the histories of Microsoft and IBM. Timothy Bresnahan, Shane Greenstein, Rebecca Henderson* Abstract: We address a longstanding question about the causes of creative destruction. Dominant incumbent firms, long successful in an existing technology, are often much less successful in new technological eras. This is puzzling, since a cursory analysis would suggest that incumbent firms have the potential to take advantage of economies of scope across new and old lines of business and, if economies of scope are unavailable, to simply reproduce entrant behavior by creating a “firm within a firm.” There are two broad streams of explanation for incumbent failure in these circumstances. One posits that incumbents fear cannibalization in the market place, and so under-invest in the new technology. The second suggests that incumbent firms develop organizational capabilities and cognitive frames that make them slow to “see” new opportunities and that make it difficult to respond effectively once the new opportunity is identified. In this paper we draw on two of the most important historical episodes in the history of the computing industry, the introduction of the PC and of the browser, to develop a third hypothesis.
